Lava flows out of Mayon Volcano on 152nd day of effusive eruption

Mayon Volcano in Albay continued to have lava flowing out of its summit crater as it marked its 152nd consecutive day of effusive eruption on Saturday, the Philippine Institute of Volcanology and Seismology (PHIVOLCS) said.

PHIVOLCS' camera captured the lava effusion at 1:52 a.m.

"The effusive eruption of Mayon Volcano continues for its 152nd consecutive day, generating incandescent lava flows, pyroclastic density currents (PDCs), locally known as 'uson,' and rockfalls," PHIVOLCS said.

"Alert Level 3 remains in effect over Mayon Volcano, and entry into the 6-km Permanent Danger Zone is strictly prohibited," it added.

In its bulletin issued Saturday, PHIVOLCS said the volcano also had lava effusion and episodic minor strombolian activity on Friday.

The lava flow on Basud Gully reached 3.8 km, while it was 3.2 km on the Bonga Gully, and 1.8 km on the Mi-isi Gully, it added.

There were also 14 volcanic earthquakes recorded Friday. These included three volcanic tremors lasting four to 41 minutes long.

A total of 210 rockfalls and two PDCs were also logged.

A crater glow remains fairly visible to the naked eye.

The volcano also emitted 1,754 tonnes of sulfur dioxide on Friday.

These resulted in moderate plumes with rose 500 meters above the crater before drifting northeast and east-northeast.

PHIVOLCS warned that aircraft should not fly close to the volcano.

Possible hazards such as rockfalls or landslides or avalanches; ballistic fragments; lava flows and lava fountaining; PDCCs; moderate-sized explosions; and lahars during heavy and prolonged rainfall may occur, it added. —KG, GMA News
